Introduction: This study analyzed intra- and interobserver agreements during radiographic assessment of the different stages of root development using the dichotomous, Moorrees, Demirjian, and Cvek classifications, as well as the effect of the observer's level of experience on the result.

Methods: Two hundred eighty-five digital periapical radiographs were examined via visual inspection by 3 experienced and 3 nonexperienced observers (n = 6) under strict technological and viewing conditions. After observer calibration, determination of the presence or absence of an open apex and the assignment of a root development stage according to the different subdivisions of the 4 indexes were performed.

Objectives: The aim of this study is to estimate the cut-off points for the Portuguese legal ages through the I, and to compare them with the methods of Demirjian, Nolla and Moorrees.

Design: The lower third molars were analyzed on 348 orthopantomography's aged between 12 and 23 years in a Portuguese Population. The images were analyzed by ImageJ and the cut-off points were calculated for the respective legal ages of 14, 16, 18 and 21 years old. Read More

Menarche is an indicator frequently used to study variation in growth, development, and related health conditions among members of living populations. As a life event, menarche is often associated with changes in an individual's social identity. The reproductive lifespan, which for females starts with menarche, is a paramount feature of palaeodemographic studies. Read More

Background: Numerous dental reference data exist to estimate age from developing permanent teeth.

Aim: To compare the performance of reference data that provide a point estimate using the developing second molar.

Methods: Performance of several methods estimating age using mandibular second molar formation was compared using the Maber test sample (age = 3-16) of 946 dental radiographs. Read More

The objective of this study of the maturation of deciduous dentition was to offer a novel age-estimation method for Mediterranean populations, using the osteological collection of fetuses, infants, and young children in the Anthropology Laboratory of Granada University (Spain) as study material. After excluding premature newborns and infants with disease, the final study sample comprised 1303 deciduous teeth suitable for analysis from 138 individuals (80 male, 58 female) aged between 24 weeks in utero and 6 years. Eleven mineralization stages were defined for the dental maturation analysis, and the alveolar emergence was also studied. Read More

Multiple third molar development registration techniques exist. Therefore the aim of this study was to detect which third molar development registration technique was most promising to use as a tool for subadult age estimation. On a collection of 1199 panoramic radiographs the development of all present third molars was registered following nine different registration techniques [Gleiser, Hunt (GH); Haavikko (HV); Demirjian (DM); Raungpaka (RA); Gustafson, Koch (GK); Harris, Nortje (HN); Kullman (KU); Moorrees (MO); Cameriere (CA)].

Objective: Age estimation methods using mandibular third molar (M3) root formation were tested. Diagnostic accuracy of M3 to predict age 18 was tested.

Design: Methods were tested on a target sample of 300 dental panoramic radiographs (age 11-25). Read More

Developing teeth are used to assess maturity and estimate age in several disciplines. The aim of the study was to determine which of the most well known dental age estimation methods was best at estimating age. The target sample of dental radiographs (N = 946, ages 3–16) was described by Maber et al. Read More

Dental age estimation of juvenile skeletal remains has utilized the methods of Moorrees ,Fanning and Hunt (1963) [MFH] and Demirjian,Goldstein and Tanner (1973) [DGT] for many years with various results. The Demirjian et al method has been tested by several authors on their population groups with varying results.The use of these methods to age the skeletal remains of South African children by the author has not been successful.

The standard age estimation methods of Moorrees, Fanning & Hunt (1963) and that of Demirjian, Goldstein & Tanner (1973) have been shown by several authors to be inaccurate when applied to their juvenile population. This was similarly found to be true in South African children. Pantomographic radiographs of samples of South African children of White, Coloured, Indian and Black origin were used to develop dental age related tables for these ethnic groups. Read More
